    Abstract: Disclosed herein are water-soluble films comprising a mixture of a water-soluble polyvinyl alcohol copolymer including an anionic monomer having a pendant carboxyl group, and a plasticizer blend comprising a first plasticizer comprising sorbitol and a secondary plasticizer selected from the group consisting of glycerol, trimethylolpropane, diglycerol, glycerol propylene oxide polymers, glycerol diacetate, 2-methyl-1,3-propanediol and a combination thereof, wherein (i) when the total plasticizer in the film is less than 12 PHR, then the plasticizer blend comprises sorbitol, glycerol, and at least one additional secondary plasticizer; (ii) when the total plasticizer in the film is at least 12 PHR and less than 20 PHR, then the plasticizer blend comprises sorbitol, glycerol, and at least one additional secondary plasticizer selected from diglycerol, trimethylolpropane and a combination thereof; and (iii) when the total plasticizer in the film is 20 PHR or greater, then sorbitol comprises at least ⅓ of the total plasticizer.
